Product Summary

The pilot operated solenoid valve is a kind of solenoid valve controlled by pilot. A solenoid valve is an electromechanical valve for use with liquid or gas which is controlled by an electric current through a solenoid. And there are some types of the valves, in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold. Besides the plunger-type actuator which is used most frequently, pivoted-armature actuators and rocker actuators are also used.
The two main parts of a solenoid valve are the solenoid and the valve. The former part converts electrical energy into mechanical energy which, in turn, opens or closes the valve mechanically and a direct acting valve has only a small flow circuit, shown within section E of this diagram (this section is mentioned below as a pilot valve). This diaphragm piloted valve multiplies this small flow by using it to control the flow through a much larger orifice.
The Solenoid valves may be made of metal seals or rubber seals, and may also have electrical interfaces to allow for easy control. A spring may be used to hold the valve opened or closed while the valve is not activated.
